I’m pretty sure it wouldn’t take me 8 years to find another chicken that looked enough like that one to fool the daughter. Problem solved.
Believe it or not, chickens have personalities and long term pet chickens can be taught tricks.
I have a friend who raises them. Each hatch, she picks out one and trains it. It follows her around, sits on her lap,comes when called, responds to its name and she would know instantly if even a lookalike was substituted.
